Werner, a brilliant and hardworking magic tool researcher at the Empire's top institution, the Sage's Academy, is suddenly expelled by a jealous chancellor who seeks to profit from his inventions. Following his dismissal, the Academy quickly finds itself unable to develop any new magic tools, as Werner's advanced theories prove impossible for anyone else to follow.

The story follows Werner after this fall from grace, which ultimately becomes a liberation from the institution's stifling politics and sabotage. Outside the Academy's rigid structure, he dedicates himself to a laid-back life of research, working at his own pace to create incredible magical artifacts. Though he dreams of peace and quiet study, his true power as an S-rank mage and his growing reputation attract attention from all walks of life, including a pragmatic princess who sees him as an ally to the kingdom and a powerful yet innocent dragon maiden. His home gradually transforms into a lively laboratory filled with curious apprentices, unexpected visitors, and adventures ranging from the comic to the epic.

The narrative is driven by the contrast between Werner’s humble, unassuming personality and his overwhelming magical abilities. As he navigates his new circumstances, the story explores his interactions with a cast that includes the envious chancellor as the initial antagonist, a group of distinctive young apprentices who bring humor to daily life, and various powerful figures drawn to his genius. The series blends fantasy, slice of life, and comedy as Werner remains focused on his research while the world around him reacts to the powerful mage they have only just discovered.
